The LCD, as a display including a color screen with a high resolution, has been widely applied to a variety of electronic devices such as mobile phones, personal digital assistants (PDAs), digital cameras, computer screens, and laptop screens. used monitor with a high resolution color screen. A conventional, widely applied liquid crystal display is formed by upper and lower substrates and a medial liquid crystal layer. The substrates are formed by glass and an electrode, etc. When the upper and lower substrates in the display include an electrode, the display is at a longitudinal electric field mode such as a twist nematic (TN) mode, a vertical alignment (VA) mode, and a multi-domain vertical alignment (MVA), which aim to address too narrow development of a viewing angle. Different from the above-mentioned display, another kind of display includes a single electrode arranged on one side of the substrate and forms a horizontal electric field mode such as an in-plane switching (IPS) mode, a fringe field switching (FFS) mode, etc.

It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures.
- A conventional tri-gate driver structure is poor for pixel charging ability so inadequate charging easily occurs. Due to inadequate charging, image display is usually lousy, further deteriorating the display quality. The defect can be well resolved with the embodiments of the present disclosure.
- According to the present disclosure, an array substrate comprises a plurality of display pixels arranged in an array. Each of the plurality of display pixels comprises a red subpixel R, a green subpixel G, and a blue subpixel B. Six of the consecutive display pixels arranged horizontally and/or longitudinally as a whole are repeatedly arranged in a pixel unit. An arrangement order of the subpixels in each of the six consecutive display pixels is totally different. The subpixels in the six consecutive display pixels are arranged as RGB, RBG, GRB, GBR, BRG, and BGR successively.
- Compared with the related art, a subpixel following a green subpixel G is a red subpixel R or a blue subpixel B in the present disclosure. The green subpixel G is constantly bright when the image displays normally. The green subpixel G is mixed with the red subpixel R under charging and the blue subpixel B under charging, which compensates the red subpixel R and the blue subpixel B for brightness. In this way, the display quality is well improved.
- The pixel transparent area on the green subpixel G is less than the pixel transparent area on the red subpixel R and the blue subpixel B. This design is a solution to color shift occurring during color mixing due to the green subpixel G with greater brightness.

FIG. 3 illustrating a schematic diagram of a pixel of array substrate according to one preferred embodiment of the present disclosure. The array substrate includes a plurality of pixel units arranged in an array. Each of the plurality of pixel units includes a red subpixel R, a green subpixel G, and a blue subpixel B. Each column corresponds to a data line. Each row corresponds to a gate line. Six pixel units arranged horizontally and/or longitudinally are repeatedly arranged in circulation in the pixel structure. - The subpixels in each of the six consecutive pixel units arranged longitudinally are arranged in a way of RGB, RBG, GRB, GBR, BRG, and BGR successively. Likewise, the subpixels in each of the six consecutive pixel units are arranged horizontally.
- Compared the green subpixel G with the red subpixel R and the blue subpixel B, some of the subpixels are not fully charged when a pure green image is shown. Some of the subpixels and the green subpixel G are mixed in colors so that the problem of color shift is resolved due to inadequate charging. Since the same arrangement of pixels is adopted in different rows, charging waveforms for different rows are identical.

FIG. 4 illustrating a schematic diagram of the pixel of the array substrate according to the preferred embodiment of the present disclosure. The array substrate includes the plurality of pixel units arranged in an array. Each of the plurality of pixel units includes the red subpixel R, the green subpixel G, and the blue subpixel B. Each column of the subpixels corresponds to a data line. Each row of the subpixels corresponds to a gate line. The six pixel units arranged horizontally and/or longitudinally are arranged repeatedly in circulation in the pixel structure. - The subpixels in each of the six consecutive pixel units arranged horizontally are arranged as RGB, RBG, GRB, GBR, BRG and BGR successively. Likewise, the subpixels in each of the six consecutive pixel units arranged longitudinally are arranged horizontally.
- Compared the green subpixel G with the red subpixel R and the blue subpixel B, some of the subpixels are not fully charged when a pure green image is shown. Some of the subpixels and the green subpixel G are mixed in colors so that the problem of color shift is resolved due to inadequate charging. Since different arrangements of the pixels are adopted in different columns, charging waveform for different columns are different.

FIG. 5 illustrating a schematic diagram of the pixel of the array substrate according to the preferred embodiment of the present disclosure. The array substrate includes the plurality of pixel units arranged in an array. Each of the plurality of pixel units includes the red subpixel R, the green subpixel G, and the blue subpixel B. Each column of the subpixels corresponds to a data line. Each row of the subpixels corresponds to a gate line. The six pixel units arranged horizontally and/or longitudinally are arranged repeatedly in circulation in the pixel structure. - The subpixels in each of the six consecutive pixel units arranged horizontally are arranged as RGB, RBG, GRB, GBR, BRG, and BGR successively. Likewise, the subpixels in each of the six consecutive pixel units arranged longitudinally are arranged in the way of RGB, RBG, GRB, GBR, BRG, and BGR successively.
- When a pure green image is shown, some of the subpixels are not fully charged compared the green subpixel G with the red subpixel R and the blue subpixel B. Some of the subpixels and the green subpixel G are mixed in colors so that the problem of color shift is resolved due to inadequate charging. Since different arrangements of pixels are adopted in different rows, charging waveforms for different rows are different. Also, since different arrangements of pixels are adopted in different columns, charging waveforms for different columns are different.
- According to the present disclosure, a liquid crystal display panel includes an array substrate, a color filter substrate facing to the array substrate, and a liquid crystal layer sandwiched between the array substrate and the color filter substrate. An array substrate comprises a plurality of display pixels arranged in an array. Each of the plurality of display pixels comprises a red subpixel R, a green subpixel G, and a blue subpixel B. Six of the consecutive display pixels arranged horizontally and/or longitudinally as a whole are repeatedly arranged in a pixel unit. An arrangement order of the subpixels in each of the six consecutive display pixels is totally different. The subpixels in the six consecutive display pixels are arranged as RGB, RBG, GRB, GBR, BRG, and BGR successively.
- The operating principle of the LCD panel in this embodiment is consistent with the operating principle of the array substrate in the above-mentioned embodiment so the present disclosure will not go into details about the operating principle.
- While the present invention has been described in connection with what is considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements made without departing from the scope of the broadest interpretation of the appended claims.
